How to extend the battery life of a MacBook

Like all MacBook owners, are you worried about your computer’s battery wearing out too quickly? Today we present you an application that can make your MacBook battery last longer. Here’s how it works.

Know the health of your MacBook battery

With the development of telecommuting, laptops are used more and more on a daily basis. Obviously this intensive use is not without its problems. The autonomous operation of these devices makes some components subject to wear. This is the case of the battery in particular.

This indispensable element is far from being eternal. Over time, the autonomy of laptops decreases due to the wear of the battery. Fortunately, there are now tools that can tell if the battery is severely depleted and needs to be replaced.

Since the arrival of macOS Catalina 10.15.5 update, MacBook owners have a battery health management utility. As its name suggests, this tool has been designed to extend the life of the MacBook battery by reducing its ageing.

If you are in the habit of leaving your computer constantly plugged into the mains, the utility will limit the time during which the battery is at 100% charge. This may seem paradoxical, but the closer the battery gets to 100%, the more it wears out.

The battery health management function is also capable of calculating when you need to replace the battery. You should know that this operation is difficult to perform by yourself because of the compactness of the MacBook case. It’s best to call in a professional.

The battery health management system is activated by default on your MacBook. However, nothing prevents you from turning it off. Please note that this operation can only be performed on a computer equipped with an Intel chip. On Macs with the Apple M1 chip, the utility cannot be turned off.

  • Click on the Apple symbol at the top left of the screen
  • Select System Preferences from the list
  • Press Battery and then Battery Health
  • Find the line entitled Manage battery life the battery
  • Uncheck the box entitled manage battery health
  • Press OK to confirm your choice

From now on your battery will charge at its maximum power whatever the conditions of use of your MacBook. It is recommended to disable this feature before a long trip. This way you’ll be sure to always have the longest battery life.
